Guide for new device type "Gosund EP2 Smart Plug" (Product Key: wifvoilfrqeo6hvu)

The problem

Since I was having trouble setting up the Gosund EP2 Plug, here is a quick guide to have it behave like this:

The device comes with 6 DPs in its original firmware:

• DP1 = State (on/off)
• DP2 = ? (is always 0 for me)
• DP4 = Current
• DP5 = Power
• DP6 = Voltage
• DP7 = ? (is always 'False' for me)

Please note:

• Since the entity IDs get created automatically, the sensor names I am using may differ from yours.
• The real values may be about ~1% off due to the way I calculate them so if this is a problem just adapt the calculations mentioned further below
• There seems to be a certain threshold until reasonable values are provided by the plug (e.g. if I try to just charge my phone it shows 0 Watts)
• Internet access may NOT be blocked or else (at least) DP4 and DP5 will show "not available" (There seems to be some way around this according to this comment but I haven't really figured it out yet)

Configuration configuration.yaml

Configuration template_sensors.yaml

The values provided by the power and current sensors don't have the correct scaling yet. You can specify the scaling for the entities themselves but I prefer to do it via template sensors because usage is more flexible. I also created a template sensor for the voltage since I don't want to see the decimal place.

plug2_power:
  friendly_name: Plug Power
  unit_of_measurement: 'W'
  device_class: power
  value_template: '{{((states("sensor.plug_dp5") | int) / 10) | int}}'
plug_voltage:
  friendly_name: Plug Voltage
  unit_of_measurement: 'V'
  device_class: voltage
  value_template: '{{((states("sensor.plug_dp6") | int) / 10) | int}}'
plug_current:
  friendly_name: Plug Current
  unit_of_measurement: 'A'
  device_class: current
  value_template: |-
    {% set currentFlow = ((states("sensor.plug_dp4") | int) / 1000) %}
    {% if currentFlow < 0.01 %}
      {{currentFlow | int}}
    {% else %}
      {{currentFlow | round(2)}}
    {% endif %}

How can I get the local key of a Gosund device?

[Eugeniusz-Gienek]

I've got this plug and I have hard time adding it to LocalTuya. The thing is that when I try to add it it says no datapoints found - thus I have to add them manually. For some reason the switch is disabled in the UI - I can't understand why. Could You help please?

i have the same problem, but with a gosund strip. hardly a could add to localtuya, but switches are unavailable
